' a Claims. c .'-229 -f 7o) This invention "relates to improvements in envelopes and isydirected -more particularly toim provements in envelopes having certain novel fea--,

remailing purposes. "The envelope of thisinvention is, simplein form so as to be economical to manufacture and may be readily-used According to special features of thel invention, an envelope has a window in one. wall thereof and a novel detachable panel member which is foldable so as to underlie the said window in order that written or printed matteron ithe panel may be seen through the window. ,The envelope is so constructed that it maybe. mailed to a prospective customer, for example, with advertising matter or the like therein-and the separable panel or return card associated with the envelope. so that if the addressee desires. to avail himself of the opportunityoffered by' the addressor, he may detach-the panelfromthelenvelope and return it to the a'ddresson' However, theenvelope of the invention is adapted for many and various uses and it is therefore not desired to be limited to any specific embodiment of the invention since many changes may be made without departing from the spirit and scope thereof.

Various other novel features and advantages of the invention will be more fully hereinafter referred to in connection with the accompanying description of the preferred form thereof and reference will be had to the accompanying drawing wherein:

Fig. 1 is a plan view of the front side of the envelope of the invention with a closing flap and the associated panel in extended relation.

Fig. 2 is a small-scale rear view of the envelope shown in Fig. 1.

Fig. 3 is a small-scale front view of the en- I velope of the invention in closed position with the associated panel inserted in the envelope. 7

Fig. 4 is a fragmentary small-scale view similar to Fig. 1, showing a modified form of the The envelope *Eof the invention is preferably formed .of relatively-pliable material-such as 4 paper by overlapping slaps so as to. provide an am-ended pocket' i. A closing flap 2 may} e'xtend from an end o'f 'one 'wall of the envelope which isadapted to befolded along the line '7 over the"opp'osit'e*wall toclose the pocket lgin theusual manner. "In the form ofthe' invention shown, the co'ver flap 2 "extends from the rear wall of-theenvelope and is foldable to "overlap; thefrontwa'll. i

Extending from 'the'outer margin'al'edgebf-the closing flap 2 is what may be called 'a' panelrnember'fi. -This panelfi isprefer ably separable from the flap 2 along a line of "-'perf-ora't'ions(= or the like-c8. i 1 H v In-lieu' of thefiap 2,i'apanel such as 2 6}- m'ay extend from the rear wall as shown in 'Fig. '4 in which case 'it will' be scored as at 28 -and-arrangedfor a hinge'acti'onl'a'ttits j'ointure w'ith the wall from which" it extends." 1

An opening'such as l2 o'f the type commonlyre- 1 ferred to in the envelope art as-a window, is provided in ""that'wall of 'the :envelope which is preferably opposite the one from which the 'c'over flap 2 orthepanelextends. Inthe forr'n of the invention shown, "the: window 12 is provided in thefro'n't wall. iIt' is desired to here point out, however, that various changes may be made in the construction, for example, the pocket of the envelope may be open at the side of the envelope instead of at the end and the closing fiap 2 or panel may extend from the side of a wall instead of the end thereof.

By folding the cover flap 2 or the panel along the line '7, the panel 6 may be inserted into the pocket 4 so that it is disposed Within the envelope in a position underlying the window 12. Of course, the panel is of such a size and the various elements are so arranged relative. to the window that when the panel 6 is in'its inserted position (shown in Fig. 3), printed or Written matter on the panel may be seen through the window. A transparent protecting member (not shown) of tissue material or the like may or may not be associated with the window 12.

It is now desired to explain some of the uses of and ways in which the. device of this invention may be used. A

If desired,the addressor may use the envelope for containing advertising material concerning his merchandise or services. The panel or return card 6 will carry on its front side (the side shown in Figs. 2 and 3) the name and address of the prospective customer while the opposite orrear side of the card 6 may carry other information such as the address of the addressor.

Thus, as will be seen, when the closure flap 2 or panel has been folded along the line '7, and the panel inserted in the envelope, the address of the addressee is visible through the window. After postage indicated at S has been applied to the outside of the envelope E, it is ready for mailing.

The front side of the panel (the side shown in Figs. 2 and 3) may serve as an order blank as 'well as a place for the name and address of. the

addressee. It may carry postage indicated at S and a place for the addressees signature. Thusif the receiver of the envelope wishes to place an order with the addressor, he may detach the card from the envelope, fill in the providedblanks and return the already addressed panel to the addressor. Not only may the panel be provided with the addressors address, but it unmistakably may be provided also with the name and address of the receiver of the order blank.

In one form of the invention, a longitudinal slot or slit such as 14 may be provided in one wall of the envelope. This slot is preferably of a length greater than the width of the panel 6 so that the panel may be readily inserted therethrough' and into the pocket 4 as shown in Fig. 3.

Also, if desired, some sort of adhesive material 10 such as envelope gum may be provided on the inside of the cover flap 2 adjacent the detaching line 8 as shown. In this way, the pocket emay.

be sealed without in any way interfering with the function of the panelfi.

The cover flap and/ or panelmay be a separate member secured to the wall of the envelope as by an overlapping portion 9. Of course, the .cover member or panel mayor may not be of the same material as'the envelope. In fact, it may sometimes be desirable that the panel 6 be formed of material which is relatively stiff as compared with the material of which the envelope itself is made.

In another way, as in Fig. 5, a panel such as 36 may be of two-ply thickness and be a continuation of the wall from which it extends. The panel is doubled upon itself with the superposed sections 38 and 40 secured together by an adhesive. In this Way an envelope of relatively thinmaterial may be used while the panel will be thicker and stiffer and the panel may be separable along a line 42.

While I have described the invention in great detail and with respect to a preferred form thereof, it is not desired to be limited thereto since many changes and modifications may be made therein without departing from the spirit and scope of the invention. What it is desired to claim and secure by Letters Patent of the United States is:

1. A container of the class described comprising in combination, an envelope provided with a pocket open at one edge having a window in one wall thereof and a flap extending from the opposite wall of said envelope at said edge adapted to be inserted into said pocket through said open edge to lie adjacent said first-named wall, said flap including a closure portion adjacent the jointure of the flap and said one wall and a panel extending from said closure portion of such size as to have a portion thereof visible through said window when said flap is inserted within said pocket.

2. A container of the class described comprisingin combinatioman envelope provided with a pocket open at one edge having a window in one wall thereof and a panel member hinged to the opposite wall of said envelope at said edge, said first-named wall being provided with a slot ex tending laterally thereof between said window and said edge and said panel member being adapted to be inserted into said pocket through said slot to lie adjacent the inside of said firstnamed wall so as to have a portion thereof visible through said window. I

3. A container of the class described comprising in combination, an envelope provided with a pocket open at one edge and a flap member connected to one wall of the envelope at said edge by a hinge, the opposite wall being providedwith a window therein, said flap member including a closing portion adjacent said hinge and a panel member extending from said closing portion adapted to be inserted into said pocket to underlie said opposite wall of the envelope so as to have a portion thereof visible through said window.
